The scripts are also available as payload-free packages, compressed and stored as. The scripts are available on GitHub via the links below:

Patch Set Update (PSU): contains all the fixes in the corresponding CPU, plus additional fixes to non-critical problems.įor more details on the differences between CPU and PSU updates, please see the link below:įor more information, please see below the jump.
